    Primary hybrid of rarely used in hybridization species (Den jenkinsii x Den lidleyi). Very compact/miniature growth inhered from Den jenkisii. Den lindleyi contributed reasonable flower count per spike. Photos of the last season bloom. This year is dedicated to replanting on bigger mount. Den Ueang Pheung 01.jpg

    Incredible flowering for such a small plant. Impressive.

    I am always bummed out about this hybrid. Unless you knew, most times you are going to call it an aggregatum. I grow lots of jenkinsii and a dozen or less specimen aggregatums. Upon looking at that I'd call it the latter.

    I wonder how often this is used to make an aggregatum population in Asian countries?

    Is it actually blooming now? It would be worth it to make this hybrid if one species or the other had an opposite bloom time (jenkinsii spring - aggregatum fall) to have possibly a twice a year bloom.

    All that said, your plant is well grown and the flowering looks great.

    Awesome, Alexey! Fantastically grown and bloomed, good to see you back posting here.

    Daniel, I agree that the former lumping of jenkinsii and lindleyi into aggregatum probably led to a lot of captive populations being what we'd now consider this hybrid or some backcross of it. I have one 'aggregatum' that I'm 90% sure is Ueang Pheung; if only it would bloom then maybe I could find out... While I generally favor lumping at the generic level I think I'm leaning the opposite way on species, mostly for this reason.

    Daniel, I think this is the hybrid....true aggregatum has many more flowers on longer spikes. But as other's have mentioned, it might be an intergrade between the 2. I have 3 plants of this hybrid and they bloom about a month later than aggregatum. Here's a picture of one of mine. 7355226008_86b5f6eb11_z.jpg

    Thank you all,

    As a non-taxonomist I cannot accept lumping of Den jenkinsii with Den lindleyi. Assigning long time established name "aggregatum" just ads humour to this situation. Here are my Den jenkinsii and Den lindleyi (aka aggregatum). Photos are old, and most likely have already been on this forum. Not only their appearance is different, I never had to give a pronounced winter rest for jenkinsii to induce blooming. My clone of Den Ueang Pheung bloomed few weeks after greenhouse was ready and all collection moved from outdoor to the warmer and more humid environment.

    Missed to answer.
    Annabanana, these photos were taken in November 2013 - highly unlikely time for Den lindliyi (aggregating) to bloom.

    Daniel, reputation of the grower from whom I have bought it and fact that I picked it as one of more than ten seedlings (not divisions), plus observations of its bloomig habit allow to talk about hybrid, not classical aggregatum.

    Sorry, thats what I call lindleyi. I do believe thats what your plant is, it looks like an intermediate between the two. I never knew the issue with the difference in name and never paid attention because I thought it was something taxonomists cared about which was accepted. I feel your well entitled to talk about the hybrid, don't let my opinions on hybrids move yours. Like I said before its a great looking plant
